ID Statement
- ID variable
INTERVAL= value
< ALIGN= value > ;
The ID statement specifies a variable that identifies observations
in the input data set.
The variable specified in the ID statement is included in the
OUT= data set.
Note that the ID variable is usually a SAS date valued variable.
The values of the ID variable are extrapolated for the forecast
observations based on the values of the INTERVAL= option.
- ALIGN= value
-
controls the alignment of SAS dates used to identify output
observations.
The ALIGN= option allows the following values: BEGINNING | BEG | B,
MIDDLE | MID | M, and ENDING | END | E. The default is
BEGINNING.
The ALIGN= option is used to align the ID variable to the beginning,
middle, or end of the time ID interval specified by the
INTERVAL= option.
- INTERVAL= value
-
specifies the time interval between observations.
This option is required in the ID statement.
The INTERVAL=value is used in conjunction with the ID variable
to check that the input data are in order and have no missing periods.
The INTERVAL= option is also used to extrapolate the ID values
past the end of the input data.
